TRUSS.

SPECIFICATION forming part of Letters Patent No. 550,811, dated December3, 1895.

Application filed July 1 5, 189 5.

To aZZ whom it may concern.-

Be it known that I, JOEL U. ADAMS, a citizen of the United States,residing at-Oincinnati, in the county of Hamilton and State of Ohio,have invented certain new and useful Improvements in Trusses; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, reference being had to the annexed drawings, whichform part of this specification.

My invention comprises a specific combination of devices wherewith thepads of a double truss can be adjusted toward or away from each other orset at any suitable inclination, the details of said devices beinghereinafter more fully described,and then pointed out in the claim.

In the annexed drawings, Figure l is a front elevation of a pair oftruss-pads embodying my invention. Fig. 2 is a horizontalsection of thesame,the pads proper being omitted and their positions indicated bydotted lines.

The connecting member of my truss is a light cross-bar A, that bowsoutwardly, as seen in Fig. 2, and has near its ends longitudinal slots aa, traversed by pivot-screws B B, that engage with plates 0 O, to whoseinner sides the pads proper c c are secured in any suitable manner.These pad-plates are usually elliptical and slotted at D D, the slotsbeing concentric with'the respective pivots B B.

E E are clamp-screws which, after passing through the slots a a'D D,engage with nuts F F, and are then headed up at c e to prevent saidscrews being disengaged from said nuts.

G G are other screws or headed pins for the attachment of the ordinarystraps that pass under the wearers body.

Serial No. 555,981. (No model.)

From the above description it is evident that by slackening the screws BB EE the pads O c O 0 can be readily adjusted either toward or away fromeach other, and after the desired change has been effected said pads areheld in place by again tightening said screws. Again, it is apparentthat these pads maybe so set as to cause their major axes to beperfectly vertical, as seen in Fig. 1; but said axes can be inclinedeither to the right or left of a vertical line after the screws E E havebeen unslackened. Furthermore, either pad can be set independently ofthe other one, and after a suitable inclination has been obtained thescrews E E are again tightened, so as to hold the plates 0 0 immovablyin place. Finally, the screws B B not only act as the centers of motionfor said plates or pads, but they also serve as pins, to which the endsof the body strap or band are fastened.

I claim as my invention The combination, in a double-truss, of the barA, having longitudinal-slots a, a, near its ends; the pivot-screws B, B,traversing said slots; the pads O c, O c, pivoted to said bar by saidscrews B B, and having curved slots D, D, concentric with said pivots;and the clampscrews E, E, that traverse said slots a, D, a, D, andengage with nuts F, F, concealed within said pads, all as hereindescribed, and set forth.

In testimony whereof I affix my signature in presence of two witnesses.
